Improve subscriber trust and deliverability by customizing the domain used to track your email activity and content. Create up to four customizations to support forms, landing pages, click tracking and assets (online version and media files).
The official definition of a CNAME is Canonical Name. A CNAME is a record that is used in the Domain Name System (DNS) to create an alias from one domain name to another domain name.
In the email industry, CNAME records can be used to customize standard domains that are used to track email links, form submissions, and more. This practice can also be referred to as "custom tracking domains", "branded URLs", or "custom subdomains".
When CNAMEs are configured, any reference to a standard tracking domain will be masked. This means when links in an email are clicked, or a hosted landing page is viewed, or a hosted form is viewed, the customer will see their configured subdomains instead of ours.
Example
You may have noticed that when you view the online version of a sent email, or visit a hosted form or landing page, that the browser address bar contains a non-descriptive URL (seen below).

This is a standard URL generated through multiple merged parameters to identify your account, content file, etc. If you prefer to control the domain seen in these instances, we offer the ability to create branded URLs in your account.
Benefits of using CNAMEs
CNAMEs help preserve your sender reputation, increase deliverability, and can even improve email click-through rates.
If you're not using CNAMEs, you’re using a shared tracking domain. Typically this is not a major concern as most ESPs keep shared tracking domains clean and reputable, but it only takes one spam campaign using a standard tracking domain to cause temporary deliverability issues.
Further, using a CNAME that includes your brand name will allow your subscribers to feel confident about clicking links in your emails. Because of this, our customers typically see an uplift in their email click activity.
Where can I add CNAMES?
You will find this functionality is Settings > Account > CName Setup.
This is a self service process that requires a few steps inside your account to generate instructions for your IT team. When your IT team completes the steps in the generated instructions, return to your account to "authenticate" each URL configured.
How-To
- Click the Settings icon and select "Account Management" from the menu.

- Then, click the "CName Setup" tile.

- Choose if the CNAME applies to the account or to all accounts on the site.

- Click the "Setup CNames" button, top right of page.

- For each section, enter desired subdomain and brand domain to be used. You may configure up to 4 customized domains for each type: tracking, assets, landing pages, forms. Click the "Save" button, top right of page.

- After "Save" is clicked, IT instruction are generated. These steps must be completed in the DNS records of your domain. Use the "Copy Instructions" button and share instructions with team. You cannot move forward until these steps have been completed. Click "Cancel" to close page at this point.

- Once there is verification from your IT team, return to CName Setup in your account to Authenticate the new subdomains. Each subdomain entered will have a separate “Authenticate” button. When clicked, Delivra makes a call to your domain's DNS to check & verify records.
- If the DNS is missing part of a record or a record does not yet exist, a failure will be displayed. Consult your IT team when this occurs to verify the provided instructions were completed.
